HYDRAULIC SYSTEM

Gravity feed from the bottom of the oil storage tank

Gravity feed over the top of the oil storage tank

H

 = Difference in height; 

L

 = The total length of the suction line, including the vertical section.

The copper pipes of 12 mm and 14 mm I.D., as shown on the tables above, may be replaced by steel pipes of 1/2”
or 3/4” Gas.

The dimension P should not exceed 10 m, to avoid
breakage of pump seals.

The dimension P should not exceed 10 m, to avoid
breakage of pump seals.

Oil lines must be perfectly sealed. The use of copper
pipe is therefore recommended. The pump suction
must not exceed 4.5 m w.c. (35 cm Hg) because be-
yond this value the pump becomes noisy.
The return line must terminate at the same level as the
foot valve; otherwise the pump may become air-locked.
